June 30 is National Social Media day — a day to reflect on how our fav platforms have changed all of our lives for better or worse. So today, we’re celebrating by taking a look back at 12 celebrities we welcomed to one of the most powerful social media sites there are: Instagram. Check out who finally joined the 21st century and got with the times below!

1. Kevin Spacey: In what was likely a move to promote season four of House of Cards, the American Beauty actor finally bit the bullet and caved to the Instagram powers that be. Using the White House as his background (“Even I like to take a selfie outside my house from time to time,” he joked), we’re gonna go ahead and say he did quite alright! (Photo via Ian Gavan/Getty)

3. Dakota Fanning: Dakota Fanning made her entry into the world of Insta doubly impactful when she chose March 8, International Women’s Day, to step on the scene. “I have been contemplating joining Instagram for a while,” she wrote of the post (a sexy shot of herself with sideswept hair in a LBD). “I could not imagine a more perfect day than #internationalwomensday. Let’s go ladies.” Let’s go, indeed, Dakota! (Photo via Matt Winkelmeyer/Getty)

4. Kirsten Dunst: Kiki joined Instagram just this March and, already, our favorite Bring It On actress is operating like a seasoned vet, posting #Caturday and #fbf shots galore — have you SEEN this epic throwback of her and an Interview with a Vampire-era Brad Pitt?

5. Pope Francis: The Pope proved that anyone’s who anyone — and we DO mean anyone — has Instagram when he joined the site in a history-making move back in March. Since posting his first shot (one of him kneeling in prayer with the caption reading “Pray for me” in nine languages), the pope has been quite active on his new account — he’s already got 107 posts to his name as of press time!

6. Halle Berry: Halle Berry not only gave us hair and vacation goals with her first Insta post, but she proceeded to use the social media site to start her own book club hashtag. Using #HBBooksfrombed, Halle shares her current reads from — where else? — her bed and encourages fellow bookworms to do the same. (Photo via Angela Weiss)

7. Mary-Kate + Ashley Olsen: Okay, okay, so Mary-Kate and Ashley don’t actually have an Instagram account (“We’ve spent our whole lives trying not to let people have that accessibility, so it would go against everything we’ve done in our lives to not be in the public,” the mysterious duo have explained) but the twins DID crack just long enough this year to take over Sephora’s account for a day and post their very first (gasp!) selfie. (Obviously they nailed it). (Photo via Larry Busacca/Getty)

8. Gloria Steinem: Much to our delight, the famed feminist shocked the pants off of us when she did the unthinkable and got hip to social media at the wise age of 82-years-young. Perhaps it was at the urging of famous fan (and Instagram pro) Emma Watson? (Photo via Craig Barritt/Getty)

10. Taylor Lautner: Taylor Lautner just may have earned the award for best first Instagram post ever when he enlisted the aid of both Adam Sandler and David Spade (though not without a bit of, uh, creative coaxing) to star in one of the site’s new 60-second videos.

12. Shailene Woodley: Our final belated Instagram bloomer (hey, better late than never, right?) is The Fault in Our Stars star, Miss Shailene Woodley, who joined Instagram just a little over a month ago. Shailene didn’t bother playing it cool, hilariously writing, “I’m going to need help. There are so many settings and buttons and options!” 22 posts later, and we’d be none the wiser, Shailene: You’re a natural. (Photo via Mark Sagliocco/Getty)
